Definitions

  • the invention relates to a machine tool according to the preamble of claim 1.
  • EP-0 232 548 A2 describes a processing station, in particular for comparatively large workpieces, preferably with a laser having processing unit described, the Processing unit also on a frame-like vertical Stand is arranged and can be moved in the X, Y and Z directions. at certain use cases, e.g. B. at a high speed and / or High-precision machining has shown that when Moving the processing unit in the Z direction high acceleration and Apply machining forces to the tool carrier. That can be too Inaccuracies in processing lead and demands a lot stable and expensive construction of the tool carrier, especially at a very large work area and high feed rate or Acceleration. It also occurs in previously known Machining centers by switching on coolant, different Coolant temperatures and changes in the hall temperature often to significant displacements between the tool side and Workpiece side.
  • a multi-spindle automatic lathe is known from DE 38 32 975 C1
  • Known frame housing which consists of a lower machine bed, a Spindle stand with switchable spindle drum, a drive stand for the drives of the machining tools and an upper crossbeam between spindle and drive stand.
  • the workspace is there penetrated by a central tube on which a longitudinal slide block is arranged on the one hand in the spindle drum and on the other hand is stored in the drive stand.
  • a movability of the spindle with the help X, Y and Z slides are not provided here. You can also only relatively small workpieces can be machined.
  • the invention is therefore based on the object of a generic Propose machine tool that does not have these problems exist and an exact positioning of the processing unit relative to the workpiece is possible.
  • This is also a frame-like structure in the Z direction emerged, even at high acceleration and Machining forces a relative movement between the workpiece carrier and Tool carrier prevented.
  • the Workpiece holder can also, similar to the tool holder, in X and Y-direction can be frame-like, so that the workpiece is easily positioned within this frame.
  • the Workpiece can be moved through the frame in the Z direction and, if necessary, in the X or Y direction Machine tool can be transported in or out of it.
  • connection carrier between the tool carrier and workpiece carrier can in particular off-center, d. H. on one or both Long sides, be arranged so that the space directly above the Processing point, e.g. B. for loading and unloading the workpiece, remains free.
  • a one-sided eccentric arrangement of a Connection carrier can have the advantage that of the opposite side a better access to the processing room is made possible.
  • connection carrier can also be fork-shaped, wherein two legs of the fork at the top of the vertical side stand of the tool holder or the workpiece holder and the opposite leg with an upper cross member of the Workpiece carrier or the tool carrier is connected. in this connection the size and shape of the workpieces Tool changing devices and the other requirements adapted constructions.
  • Figure 1 is on a machine base 1 from vertical Sidewalls 5 and horizontal crossbar 4 existing Tool carrier 3 and in parallel opposite one from vertical supports 7 and upper cross members 6 formed Workpiece carrier 2 shown.
  • the horizontal crossbar 4 and the upper cross members 6 are connected to one another via a connecting member 8 connected.
  • connection carrier 8 is fork-shaped and with a leg 8c attached to the upper cross member 6 while the ends of the two legs 8a and 8b with the horizontal crossbar 4th can be connected.
  • the leg 8c can correspond to the spatial conditions and the strength requirements in the middle or be attached off-center or at one end of the cross member 6.
  • FIG. 4 shows the manner in which the work spindle 15 is movable within the frame-like tool carrier 3. Is to first a frame-like X-slide 10 in horizontal guides 9 Can be moved in the X direction. In addition, the again frame-like Y-carriage 12 movable on vertical guides 11 in the Y direction. In addition, the quill-like Z-slide 14 is integrated Motor working spindle in the horizontal guides 13 in the Z direction traversable.
  • the tool carrier 3, the X slide 10 and the Y slide 12 can be made hollow and provided with circulation cooling become.
